GEORGE H. LYNE, OF EAST ORANGE, NEW JERSEY.

SANDING DEVICE.

Application filed. January 28, 1915.

To all whom it may concern:

Be it known that I, Gnonon H. LYNE, a citizen of the United States, residing at East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Sanding Devices; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to sanding devices for traction elements for railway rolling stock.

My invention is particularly intended for use in connection with the traction wheels of trolley cars in cases where the rails become slippery, either from ice, or grease, or deposit of moisture or slime.

My invention is related particularly to means by which sand may be taken from the sand hopper and delivered directly upon the top surface of a rail with'economy and certainty.

In the accompanying drawings :-Figure 1 is a side view of my device unattached; Fig. 2 a. horizontal section on the line waa; Fig. 3 a vertical section with the bucket spout elevated; Fig. l a similar section with the bucket spout depressed into working position; Fig. 5 a section on the line y-g and Fig. 6 a vertical section through the structure of Fig. 1., looking toward the left.

0n the ordinary trolley car a sand box is always provided, and means for opening a valve or door is usually provided, whereby sand may be dropped either directly or through a hose upon the track.

My device is intended to be attached to and made part of a sand spout, and I have shown in Fig. 6, at a a screw connection by which this may be done. The first part of this attached spout extends vertically, as shown at h, then horizontally in the form of an elbow, and again vertically as shown in said figure. The final portion of this pipe h I make square in cross section, as shown in Fig. 5; the side of the square being about the same as the diameter of the circular cross section of the other upright and of the elbow. This gives me at the final discharge end a slightly enlarged area of cross section which prevents sand from clogging or choking the channel in its descent from the horizontal portion.

In the horizontal or elbow portion I Specification of Letters Patent.

mount a stirrer f, which is intended to loosen and start the sand. This stirrer is mounted upon a shaft extending through one wall of the plpe or conduit. Attached to this shaft, and swinging with it, is a bucket Z) provided with an enlarged or bayed portion 6, just below the final discharge of the spout and concentric with the axis thereof. This bucket is tiltable from the position shown in Fig. 3, which is the position of rest, to that of Fig. 4, which is the position of use. As it tilts, it carries with it the shaft 7" on which the stirrer f is mounted; hence whenever the bucket is turned or tilted the sand in the horizontal or elbow portion is started or agitated.

On one side of the shaft the said bucket is provided with a spout S, which is of some what larger cross sectional area than the pipe h, whereby choking is prevented. On the other side of the pivotal mount I provide a counter-weight w. This counterweight is so arranged as to keep the dis charge end of the spout normally in raised position. Of course, other means, such as a spring, or a latch, might be used.

The outer end of the spout S is provided with a lid Z, adapted to close the spout tight when the latter is in its raised position to keep out moisture, and to prevent the sand from packing. To the underside of this lid is attached a rod 1" of stiff wire, in which is formed a coiled or spring portion 8. The other end of this rod is secured to the lower part of the sand spout and below the pivotal point of the bucket.

It will be noted that when the bucket is in the position shown in Fig. 3 the distance between the point of attachment at the end of the sand spout of the rod 1" and its point of attachment to the lid Z is greater than the distance between the same two points when the bucket is tilted, as shown in Fig. 4. It

will be noted that thus the rod 1' has a pulling or tensioning effect in the position of Fig. 3, and a thrusting or pushing effect when in theposition shown in Fig. 4. In one position it tends to hold the lid Z down, and in the other position it tends to push the lid Z to its open position.

In the arm w, which carries the weight w, I provide an aperture or opening is to which a wire may be attached, running up either close to the hand of the operator, or attached to the lever which controls the current of the motor. When this rod or wire is raised,

of course, the bucket is tilted, the sand in the elbow is stirred or agitated and discharge occurs through the square end of the pipe h, the lid Z is lifted from the mouth of the spout and the sand pours through the device and onto the surface of the rail or of a wheel at a' rate which may be regulated as desired from above. As soon as the pull on the lever w ceases, the weight pulls the bucket back into position and the lid of the sand box becomes closed at once. Any sand which may drop through the spout 72, before complete closure is affected is, of course, caught in the tilted bucket and held there, and more or less forms a seal for the mouth of the pipe or conduit h.

I have shown at 0 means whereby the bucket may be covered, the weight w being here shown as attached to the cover.

I have shown at 5 means whereby a seal may be made between the fixed sand pipe and the turning or tilting bucket. This seal is very desirable to keep out moisture. Trolley cars running through wet and flooded districts, or running in a snowstorm, are apt to become spattered underneath with mud and moisture. It is desirable to keep moisture from the sand bucket and pipe, as wet sand is very apt to clog or cake and will not work well. In the form of seal shown, moisture is excluded most conveniently.

At 0 I show a bearing to which lubricants may be applied for the easy turning of the shaft which carries the stirrer or agitator f. It will be seen that in the device herein described I have provided an easy, efficient and certain means for effecting the sanding of a railway track. As soon as the arm w is lifted, the valve in the sand box being open, sand begins to pass through. The rate of its passage can be controlled from the box by the driver. Usually a mere trickle is enough. If more is desired, or if the device is intended to be used for a sand car, after which are to follow a number of trolley cars, of course, the entrance should be wider.

Having thus described my invention what I claim as new and desire to secure by Letters Patent of the United States is '1. In a sanding device for railway traction devices, in combination, a sand box, a spout therefor, a tiltable bucket mounted upon the end of said spout, means to keep said spout normally elevated, sand stirring means and means whereby said bucket may be tilted so as to actuate said stirring means and to bring the mouth of said spout near a surface to be sanded.

2. In a sanding device for railway traction device, in combination, a sand box, a spout therefor, a bucket mounted upon the end of said spout to tilt in a vertical plane. a spout for said bucket at one side of the tilting line, a counter weight at the other side of said tilting line adapted to keep the end of said spout elevated, and means whereby said counter weight may be elevated to depress said spout near a surface to be sanded.

3. In a sanding device for railway traction devices, in combination, a sand box. a spout therefor, a tilt-able bucket mounted upon the end of said spout, means to keep said spout normally elevated, means whereby said bucket may be tilted so as to bring the mouth of said spout near a rail, a lid for closing the mouth of said spout when elevated, and means whereby said lid is lifted when the spout is depressed.

5. In a device for discharging granular material, a tiltable bucket therefor having means for keeping said spout raised, a lid closing the mouth of said spout when raised, means for depressing said spout, and means for holding said lid in closed position when the spout is raised and also holding the lid in open positionavhen the spout is depressed.

7. In a sanding device, a sand box, a spout connected thereto, an elbow or horizontal portion in said spout, a tiltable bucket mounted on said spout to tilt on an axis centerwise of said elbow, a shaft to which said bucket is secured, and a stirrer also mounted on said shaft and adapted to agitate sand in said elbow.

8. In a sanding device, a sand box, a spout connected to said box, two vertical parts to said spout, a horizontal part connecting said vertical portions, a stirrer in said horizontal portion and a tiltable bucket mounted to tilt when the stirrer is actuated.

9.
